Extracted text: a) A channel has a S/N Ratio of 30 dB. Find the ratio C/B of this channel where C= channel capacity and B = bandwidth of the channel. b) The thermal noise power (Pn) available from a resistor (R) is equal to -140 dBm. If the thermal noise voltage across the resistor is 56.57 nano volts, find the value of the resistor.
